In the central part of the country, a vast alluvial plain, rice fields are everywhere. You must of course see the Mekong, a gigantic river arriving from Tibet, which runs to Vietnam and forms a large part of the Indochinese peninsula. Almost three miles wide in places, the Mekong runs over around 190 miles of Cambodia, and then Vietnam, before reaching the China Sea. This is the longest river in south-east Asia, and only the Amazon can compare with it with regard to the diversity of the aquatic fauna.
